For IF5 draw an appropriate Lewis structure. Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.
Consider the bronsted-lowry reactions taking place in these solutions. Indicate the type of Bronsted-Lowry species that characterizes the acid-base chemistry of the referenced solution.
Briefly explain why you would expect benzoic acid to be soluble in the two solvents water and dicloromethane
How much heat (in kJ}) is evolved in converting 1.00 {mol} of steam at 160.0C to ice at -55.0C? The heat capacity of steam is 2.01 {J}}/{{g.C}} and of ice is 2.09 {J}}/{{g.C}}.
2-chlorobutane reacts much more slowly than 2-chloro-2-methylpropane in the silver nitrate test. Explain this difference in reactivity
Calculate the number of kilograms of helium needed to inflate a balloon to a volume of 100,000 L at an atmospheric pressure of 250 mmHg and a temperature of -35 °C.

Match the following physical and chemical properties with the compounds cyclohexane,C6H12 , or calcium nitrate, Ca(NO3)2. CHOICES: A: C6H12 or B: Ca(NO3)2
Calculate the freezing point depression of a solution containing 0.20% wt/v glucose (mol wt of 180) and 0.5% NaCl
In this experiment a hot metal block at 100oC is added to cold water in a calorimeter. The heat lost by the metal block equals the heat gained by the water and the two end up at the same temperature.
In PLP catalyzed reactions, the bond broken in the substrate molecule must be perpendicular to the plane of the pyridinium ring. Describe why this arrangement stabilizes the carbanion
